Q. 12

A topper wire of

Answer :

1.164 × 10^-6 cm²

Given, cross-sectional area,

Tension in the wire,

Young modulus of the wire,

We know, stress,

And strain is given by ,

Young’s modulus then becomes,

therefore, longitudinal strain becomes,

Let the circular cross-section be of diameter

Given, Poisson’s ratio

hence, lateral strain

We know, area is given by
